[USRP-users] Re: N210 + UBX Power Calibration

Thanks Marcus, Basically, I'd like to have a rough idea of the power at the antenna input of the SDR, within say ±0.5 dB. Measuring two different UBX DB's on the same N210 MB, there's a significant difference in the response, especially below 100 MHz. The measurement setup was a sig gen connected

[USRP-users] Re: Struggling to build kernel and userspace for x400

Emil, it's all in the repos (MPM/UHD/FPGA, but also partly in our OE stack as we have some custom kernel drivers). Like Marcus said, this isn't something we can provide a lot of assistance with, but you can find all the code in our repos. If you have access to an X410 (or an E300 or N300 series US

[USRP-users] Re: Building custom OE sdimg for E310 / can't find radio module

Maybe incorrect CMake flags? You need to build MPM with -DMPM_DEVICE=e31x and UHD needs to -DENABLE_E300=On (although that's the default). On Fri, Sep 3, 2021 at 1:06 AM wrote: > I decided to tackle building an image from scratch, so I could pull in > software packages with complicated dependenc

[USRP-users] USRP X410 Transmitted signal distortion

Hi all, We observed a signal distortion problem with the signal transmitted by USRP x410. Use x410 to repeatedly transmit a known random signal, and then use x310 or x410 to receive. The transmitted baseband IQ data and the received signal are used for calculating cross correlation coefficient

Maybe problems in the uhd recipe? I had to do this: https://github.com/balister/meta-ettus-1/commit/bb43f3c94da02a67dfb2dfd7db83037c201515cd Philip On 9/9/21 10:34 AM, Martin Braun wrote: > Maybe incorrect CMake flags? You need to build MPM with -DMPM_DEVICE=e31x > and UHD needs to -DENABLE_E300

[USRP-users] Re: Disabling property_propagation_active - [ERROR] [RFNOC::GRAPH::DETAIL]

I have also run into this issue and thought it was just a gnuradio issue. I tried setting the last parameter of connect() to True, but it had no effect. I then found that there was a loopback cpp example provided by the uhd library. Well, that gives the same error. Is this a “feature” that has b
